Title: Optical pickup head device
Inventor: KADOWAKI SHINICHI
IPC: G11B7/135
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To lower the price and improve the reliability by making a photodetection part and an optical detector small-sized and making it hard for diffracted light generated in a hologram grating area to enter the aperture of a lens and a diffraction grating area. SOLUTION: This optical pickup head device makes it harder to make primary diffracted light enters the aperture of a lens 8 than a conventional optical pickup head device which is given lens operation in an X direction. Therefore, the angles of diffraction of primary diffracted lights 73 and 74 generated in the holographic grating area 7B can be made less than those of the conventional optical pickup head device, so photodetection parts 3A-3J of the optical detector 3 can be formed at the center part of the optical detector 3. Consequently, the optical detector 3 can be made small-sized.

Title: Multi-drawing method
Inventor: YAMADA HIROSHI
IPC: B43K1/12
Filed: 1989-10-05
Abstract: PURPOSE:To smoothly draw characters of many kinds of thicknesses by forming the tip of a general round core having a circumferential side surface into an oblique cross-section to draw various characters. CONSTITUTION:The tip of an almost round core having a circumferential side surface is formed into an oblique cross-section to draw a character. As the almost round core, for example, a column, a general trigonal prism, a general diamond column or a chestnut column are designated and, pref., the oblique cross-section of the columnar core is used. The factor of 'roundness' becomes a writing brush like character and, when a character is drawn by a respective part, five kinds of fundamental thickness can be separately written and drawn. That is, by forming one round core into an oblique cross-section, extremely slender writing due to rear peripheral surface part/nib side, slender writing due to the nib side outer angle, medium slender writing only due to the tip part of six oblique cross-sections, writing in medium bold strokes due to both side part angle (curve) positions of seven oblique cross- sections and writing in bold strokes due to total eight oblique cross-section positions can be performed. Especially, when a character is drawn by the contact surface of an oblique cross-section tip part, the delicate touch of a writing brush is created by the intensity of pressure. Further, writing in bolt strokes becomes thick 8 under high pressure of 6. When pressure is reduced, slightly slender medium drawing can be performed.

Filed: 1988-10-19
Abstract: PURPOSE:To promote the durability by suppressing the reproducing of a magnetic floppy disk and a magnetic head for a still picture reproducing means when a sound reproducing means is not under the reproducing state. CONSTITUTION:When the reproducing of an audio cassette tape 8 is stopped by an audio cassette reproducer 20 in order to discontinue a program for some reason, this matter makes a disk drive control part 24 work via a disk drive control signal line 40, so that the rotation of the magnetic floppy disk 26 by a motor 38 is stopped, and simultaneously the magnetic head 28 is withdrawn from the magnetic floppy disk 26. Thus, when the audio cassette tape 8 is not under the reproducing state, the rotation of the magnetic floppy disk 26 by the motor 38 in the still picture reproducing device 18 is stopped, and on the other hand, since the magnetic head 28 is withdrawn from the magnetic floppy disk 26, the magnetic floppy disk 26 and the magnetic head 28 can be prevented from abrading wastefully.

Abstract: PURPOSE:To prevent temperature-rise in the exhaust port of a high-pressure turbine so as to reduce disturbance in e power transmission system, at the process of stopping a turbine plant, by breaking steam supply to the high- pressure turbine under the particular condition, and exhausting steam in the high-pressure turbine into a condenser. CONSTITUTION:There is provided a comparison arithmometer 22 which compares the inner pressure 20 in a high-pressure turbine 4 with the reheat steam pressure 21 thereof so as to calculate its deviation. The comparison arithmometer 22 fully closes the governor 3 of the high-pressure turbine when the deviation becomes below the specified value. While the governor 3 of the high-pressure turbine is fully closed, a steam dump valve 17 opens so that steam in the high-pressure turbine 4 is exhausted into a condenser 11. Therefore, it is possible to prevent temperature-rise in the exhaust part of the high-pressure turbine, hence ensuring reduction of disturbance in a power transmission system at the time of turbine trip.

Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To prevent a moire fringe in a region of a skin color from being emphasized. SOLUTION: There is disclosed an electrophotography using toner of C, M, Y and black. Image representation data is generated such that a screen angle of a mesh point among colors is shifted by about 90 deg./4 (=22.5 deg.), then a screen angle between Y and M is separated by more than 15 deg. which is an angle heretofore employed so that a moire fringe is made inconspicuous. Moreover, for example, a screen angle of Y is set to about 5 deg. or about 10 deg. which is away from 0 deg. or 90 deg. and each of screen angles of other colors are shifted by about 22.5 deg., then the screen angles of Y in the vertical and horizontal directions are eliminated so that interference of a character or an image with a vertical or horizontal line can be prevented.  A multi-dither method utilizing a conversion table having a correspondence of gradation data with a plural kinds of driving signal data of dots of beams for representation of the electrophotography is adopted so that the multi-gradation representation with high resolution can be realized by few dots per unit area and the setting of a specific screen angle can be facilitated.

Title: Control device for automatic transmission
Inventor: SUZUKI AKIRA
IPC: F16H61/08
Filed: 1991-10-09
Abstract: PURPOSE:To prevent a speed change shock from being generated in the case of judging the second speed change during the simultaneous speed change of a main and sub speed change units. CONSTITUTION:A servo hydraulic control means for controlling oil pressure in a hydraulic servo controls the oil pressure in the hydraulic servo by an electric signal by disconnecting the hydraulic servo from an accumulator in the case of executing a simultaneous speed change. In the case of judging the second speed change by a speed change judging means during the simultaneous speed change, while a rotational speed detected by a rotational speed detecting means is monitored, the oil pressure in the hydraulic servo of a friction engaging element for a down shift is controlled by the electric signal and returned to a condition before the simultaneous speed change. In this way, a specific speed change stage is formed, and after the specific speed change stage is formed, a speed change signal by the second speed change judging is output to a hydraulic control circuit. Since the speed change signal by the second speed change judgment is not output to the hydraulic control circuit before the specific speed change stage is formed, the hydraulic servo is kept in a condition wherein it is disconnected from the accumulator.
